Google seems to be inciting the wrath of liberals as it courts more conservatives.

A couple dozen protesters showed up at the search giant’s Mountain View campus on Tuesday afternoon to protest the company’s financial support for the American Legislative Exchange Council. The protesters, who described themselves as climate activists, characterized ALEC as a peddler of “denial” about climate change.

A spokesman for ALEC, Wilhelm Meierling, took issue with that characterization, describing it as a conservative non-profit group that promotes limited government and free-market policies. He declined to comment on the protest.

Google did not respond to a request for comment.

Google was just one stop on the Silicon Valley tour for the protesters, who were affiliated with Forecast the Facts and Common Cause. They also dropped by Facebook and Yelp and planned to pay Yahoo a visit as well. All have provided funding to ALEC.
